下面简单的介绍一下指针式万用表的使用注意事项;量程转换开关必须拨在需要测量的档位上,不能放错,如果测量电压时误将转换开关拨在电流档或者电阻档,则将会损坏万用表。在测量电流或电压时,如果对于被测电流、电压大小心中没有数,应该先拨到最大量程上,以确保指针(表头)不至于打坏,然后再拨到合适的量程上测量,以减小误差。但是切记不可以带电转换量程开关。在测量直流电压或直流电流时,必须注意万用表表笔的极性。正负端应各与电路的正负端相接。

变频器保养:每台变频器每季度要清灰保养1次。保养要清除变频器内部和风路内的积灰,脏物,将变频器表面擦拭干净;变频器的表面要保持清洁光亮;在保养的同时要仔细检查变频器,察看变频器内有无发热变色部位,水泥电阻有无开裂现象,电解电容有无膨胀漏液防爆孔突出等现象,PCB板有否异常,有没有发热烧黄部位。保养结束后,要恢复变频器的参数和接线,送电,带电机工作在3Hz的低频约1分钟,以确保变频器工作正常。变频器大修变频器具体大修项目主要依据变频器使用年限以及日常检查的结果决定。
Self-supporting full-plastic cable (HYAC) : self-supporting full-plastic cable has two kinds of concentric structure and calabash structure. The commonly used HYAC full-plastic cable is calabash structure. Wire: annealed bare copper wire with diameter of, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9; Color the insulation line according to the full chromatographic standard. A single insulated wire is twisted in pairs at different pitch to minimize crosstalk and a specified chromatographic combination is used to identify pairs of wires. Cable core: the cable core structure is based on 25 pairs of cables. More than 25 pairs of cables are assembled according to the unit. Each unit is wrapped with the unit of specified chromatogram to identify different units. More than 100 pairs of cables plus 1% of the reserve pair. Shielding: the shielding layer is made of corrugated metal tape which is wrapped vertically on the outside of the cable core wrap belt and firmly bonded on both sides. The metal strip of the shielding layer is coated with plastic film to facilitate bonding with the sheath to prevent corrosion of the shielding layer. Protective sleeve: protective sleeve is black low density polyethylene, can use double protective sleeve according to the need.
